8 iClaims.

The main objects of this invention are:

First, to provide an improved method of making basket or receptacle liners resulting in very economical production of the liners.

Second, to provide an improved basket liner or receptacle which adapts itself to variations in size and shape of the baskets, such as occur in ordinary manufacturing, without injury to the contents.

Objects relating to details and economies of my invention will appear from the description to follow. The invention is defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is illustrated in the accompanying drawing, in which:

Fig. 1 is a perspective view of my improved basket liner partially opened up for insertion in a basket and partially severed, the severed portion being turned back to better disclose the structure.

Fig. 2 is a fragmentary perspective view illus-' trating one of the steps of manufacture and the collapsed liner.

Fig. 3 is a fragmentary perspective view of th opposite side of the parts shown in Fig. 2.

Fig. 4 is a fragmentary inside view of the opened or erected liner.

Fig. 5 is a fragmentary outside view of the liner opened. or erected.

Fig. 6 is a fragmentary outside view of the embodiment shown in Fig. 5 showing the ends disengaged to permit expansion.

I am familar with the disclosure of Patent No. 1,927,218, dated September 19, 1933 to Robert H. Rutledge. In general, such patent discloses a package or basket liner formfl of a strip of fibrous material such as heavy paper or light cardboard having its ends overlapped and secured by staples. The portions of the strip into which the staple prongs or ends are clinched are partially severed from the body of the strip by a series of slits or perforations providing break-out portions which are readily broken from or fractnrable from the main body of the liner when the liner is subject to stress as may be exerted by the contents, thereby allowing the liner to expand into supporting engagement with the wall of the receptacle.

In basket liners such as disclosed by the Rutledge patent, the most practical way of manulecture is to drive the staples so that their arms 1934, Serial No. 742,109

so that the projecting ends may injure the contents of the basket particularly when the baskets are packed with fruit. It is also desirable to use light gauge staples.

I have, in my copending application for patent, disclosed and claimed one method of forming basket liners, overcoming these objections, and the subject matter of this application likewise overcomes the objections and in certain respects has substantial advantages over that of my said copending application.

In the accompanying drawing, 1 illustrates my improved liner which is formed of a strip of heavy paper or light cardboard or other suitable fibrous material having overlapping ends 2 and 3, the overlapping end 2 being a flap connected'to the end 4 by the scored or folding line 5. The strip is folded upon itself, there being a folding line 6 opposite the folding line 5. The openings 7 are ventilating openings.

These liners are shipped in the flat, being collapsed upon the fold lines 5 and 6, a fragment of the collapsed liner being shown in Figs. 2 and 3, Fig. 2 being an inside view and Fig. 3 an outside view. The liner is not shown completely collapsed in these figures as the ends are separated for convenience in illustration, but it will be understood that they normally lie flat upon each other until opened or set up for use.

In manufacturing the liners, the material from which theliners are formed is cut into strips and pref -rably at the same time the ventilating openings 7 are formed and also the annularly disposed series of slits 8 forming the break-out portions 9 and the annularly disposed series of slits 10 forming the break-out portions 11. The score lines 5 and 6 may also be formed at the same time.

In preparation for stapling, the strips are folded on the folding line 6 and the flap 2 folded over the end 3 in which positionv the corresponding break-out portions 9 and 11 are in opposed relation. The staples 12 are driven or inserted through these break-out portions and the interposed end 3 and clinched at 13 on the breakout portion 11. As the liners are in the fiat, all the staples, threebeing illustrated, may be inserted at the same time by a multiple head stitching machine, and the folded liner can be automati-- cally fed thereto.

It will be observed that the holding portions 14 of the break-outs 9 are much smaller than the holding portions 15 of the break-outs 11 so that when the liner is opened up from the fiat, as' shown in Figs. 2 and 3, the break-outs 9 are readily severed or broken out of the strip, forming disk-like washers or reinforcing members for the staples, as shown in Fig. 4. This quite effectively insures that when the liner is placed under stress, such as would disrupt or break the 5 hold of the staples, or open the staples, that the prongs will open up or be torn out of the outer portion or flap portion 2 in the event that the break-out portion 11 is not employed, as shown in the embodiments of Figs. 5 and 6, or in the event that it does not give way. While I preferably form the liners with the break-out portions 11, quite satisfactory liners may be formed without these break-out portions, as shown in Figs. 5 and 6, inasmuch as the staples and the inner 15 portion of the liner engaged by the bights of the staples are reinforced by the disk or washer-like break-out portions 9.

The staples preferably are and may be with this arrangement of parts, formed of light stock or gauge of wire strands, such for example, as used in stitching the signatures of books. My improvements permit the use of standard types of stapling machines. This method of manufacture results not only in desirable liners but may be very economically practiced.

I have illustrated my improvements as embodied in basket liners of the so-called tub or straight-side type. I have not attempted to illustrate or describe my improvements in the various adaptations I contemplate as it is believed that this disclosure will enable those skilled in the art to embody or adapt my improvements as may be desired.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. The method of making endless ba'sket liners of the character set forth from a strip of material which comprises the steps of providing an end flap at one end of the strip and forming breaktion, positioni g the other end of the liner strip under said-end flap, and inserting staples through the aligned break-out portions and the interposed end of the strip with the bights of the staples engaging the break-out portions in the strip and the prongs engaging the break-out portions in the flap, the break-out portions in the strip being substantially weaker than those in the flap so that the break-out portions engaged by the bights of the staples are readily severed from the liner strip when the liner is opened or set up for use. 2. The method of making endless basket liners of the character set forth from a strip of material which comprises the steps of providing an end flap at one end of'the strip and forming break-out staple receiving portions in the end flap and in the strip adjacent said end flap positioned so that when the flap is folded the breakout portions of the strip and flap are in opposed relation, positioning the other end of the liner strip under said end flap, and inserting staples I are readily severed from the liner strip when the liner is opened or set up for use.

3. The method of making basket liners of the character set forth from a strip of material which comprises the steps of folding the strip longitudinally uponitself with one end projecting beyond the other, and folding such projecting end upon the other end, the end of the strip having the folded end and the folded end thereof having opposed break-out portions, and. inserting staples through the break-out portions and the interposed end of the strip, the break-out portions in the strip being substantially weaker than those in its folded end so that the breakouts of the strip are readily severed from the .liner strip when the liner is opened or set up for use.

4. The method of making basket liners of the character set forth from a strip of material which comprises the steps of folding the strip longitudinally upon itself with one end projecting beyond the other, and folding such projecting end, the end of the strip having the folded end having break-out staple receiving portions, and inserting staples through such break-out portions and the superimposed parts so that when the liner is opened or set up for use such breakout portions are severed from the strip and constitute reinforcing members for the staples, the bights of the staples engaging such reinforcing members.

5. As a new article of manufacture, a collapsed basket liner having an attaching flap at one end overlapping the other end, one of the folds of the collapsed liner coinciding with the fold of the flap, the superimposed ends and flap being secured together by staples, the end having the flap and the flap having opposed break-out portions engaged by the staples, the break-out por-' tions of the end having the flap being engaged by the bights of the staples and being substantially weaker than the break-out portions of the flap engaged by the clinched prongs of the strips so as to be broken out when the liner is opened or set up for use.

6. As an article of manufacture, a collapsed basket liner comprising a' fibrous strip having an attaching flap at one end, the flap being fold?- ed over the other end, the end having the flap and the flap having opposed break-out staplereceiving portions, and means connecting said opposed break-out portions together, the breakout staple-receiving portions of the strip being substantially weaker than those of the flap so that they are severed when the collapsed strip is opened up for use.

7,. As a new article of manufacture, a collapsed basket liner having an attaching flap "at one end overlapping the other end, one of the folds of the collapsed liner coinciding with the foldof'the flap, the superimposed ends and flap be-; ing secured together by staples, the end havingthe flap having. break-out portions engaged by the staples, the break-out portion being engaged by the bights of the staples and being severed from the strip whenthe liner is opened or set up for use.

8. As an article of manufacture, a collapsed basket liner comprising a fibrous strip having an having the flap having break-out staple-receiving portions so that-they are severed when the collapsed strip is opened up for use.
